Status of State-Led Basin-Wide Feasibility Studies Briefing to theCentral Valley Flood Protection Board June 28, 2013
Today’s Briefing • Purpose and Scope of Basin-Wide Feasibility Studies • Planning Approach to BWFS • Activities to Date • Board Briefing Schedule …“some ideas”
State Systemwide Investment Approach Relative Comparison of Preliminary Approaches to State Systemwide Investment Approach (from 2012 CVFPP)
Geographic Scope of Studies DWR has launched two Basin-Wide Feasibility Studies (BWFS) to refine the physical improvements broadly described in the 2012 CVFPP • Sacramento River Basin • San Joaquin River Basin
Purpose of BWFS… … is to evaluate the feasibility of different alternatives for improving the flood management system, consistent with the SSIA, including • Improving flood management system flexibility and resiliency through expansion and extension of the flood bypass system and other system improvements • Integrating ecosystem enhancements and other multi-objective projects with systemwide flood management improvements • Combining regional improvements with system improvements to identify the State’s systemwide investment package.
Scope of BWFS Refine SSIA System Improvements • Weir and bypass system expansion • New bypasses • Flood system structure modifications • Conjunctive use and groundwater recharge • System operational changes through coordinated reservoir operations • Mitigation features (for potential flood stage increases of other improvements) Focus of Activities to Date
Planning Approach • Specify problems and opportunities • Inventory and forecast conditions • Formulate alternative plans • Evaluate effects/screen alternative plans • Compare alternative plans • Select recommended plan
BWFS Development Milestones Continuous integration with Conservation Strategy development Phase 1 Phase 2 M6 - Final BWFS Report Study Initiation M1 - Identify Basin Problems, Objectives & System Improvement Features M2 - Formulate Alternative Options M3 - Identify Preferred Option M4 - Public Draft BWFS Report M5 - Public Comments and Revisions 2013 2012 2014 2016 2015 Integration with Regional Flood Management Plans
Technical Analysis Process Phase 1 Phase 2 Step Step Step Step 1 2 3 4 Identify & evaluate potential bypass improvement features Formulate bypass system options (Combination of Features) Compare preliminary plans & explore trade-offs Refine & confirm recommended basin-wide plan Compare benefits & costs systemwide, & evaluate tradeoffs Option 1 Evaluate & compare individually Evaluate & compare combinations Preferred Option Option 2 Option 3

Activities to Date…and continuing • Problem Identification • Objectives • Technical data and analyses
Problem Identification & Objectives Problems What do we want to achieve? What do we measure? How much is needed to achieve the results? Objectives Management Actions SSIA Refinement: What actions best achieve the objectives? Implementation Are we making progress? Do we need to adjust our actions? Monitoring
Draft Objective Topics Basin-Wide Feasibility Study Objective Topics 2012 CVFPP Goals • People and property at risk • Flood system flexibility • Flood system resiliency • Floodplain management • CVFPP Primary Goal: • Improve Flood Risk Management • CVFPP Supporting Goals: • Promote Ecosystem Functions • Improve Operations and Maintenance • Improve Institutional Support • Promote Multi-Benefit Projects • Ecosystem Processes • Habitats • Species • Stressors • Long-Term Cost of O&M • Consistent and Efficient O&M Practices • Collaboration • Sustainable Funding • Information and Tools • Project Approvals • Integrated Water Management
Measureable Objectives Development • Pubic Workshop held on May 2nd • Next steps • Review of comments received • Technical analyses to inform refinement of objectives • Consideration of level of detail of objectives to be displayed in BWFS and 2017 update to CVFPP • 2nd Technical workshop in Fall 2013
